|Growth of Mushroom‐like Carbon Nanotubes and Nanodiamond Directly on Hydroxyapatite via MPECVD|
Mushroom‐like carbon nanotubes (CNTs) and sphericalnanodiamond, 3 nm in diameter, have been successfullygrown directly on hydroxyapatite (HA) via microwaveplasma enhanced chemical vapor deposition (MPECVD) forthe first time. The diameter of the CNTs was found to be notuniform while its length was about 500 nm. The HA partiallytransformed to the β‐tricalcium phosphate throughdehydroxylation. In all samples, the intensity of the G‐bandwas higher than that of the D‐band, which indicates th...

|A Liquefier for Mars Surface Propellant Production - Salerno, Lou J.|
NASA's planned Mars exploration missions will require that cryogenic propellants be manufactured on the surface. The present scenario calls for oxygen and methane gases to he produced using the carbon dioxide atmosphere plus seed hydrogen brought from Earth. Gases will require liquefaction for both storage on the Martian surface and for use in the ascent vehicle. The planned liquefaction rates range from 12.6 g/hr of oxygen for the 2003 robotic mission to 2500 g/hr for the later human missions...

|VEGF165 Stimulates Vessel Density and Vessel Diameter Differently in Angiogenesis and Lymphangiogenesis - Parsons-Wingerter, Patricia|
Vascular endothelial growth factor-165 (VEGF(sub 165)) stimulated angiogenesis in the quail chorioallantoic membrane (CAM) by vessel expansion from the capillary network. However, lymphangiogenesis was stimulated by the filopodial guidance of tip cells located on blind-ended lymphatic sprouts. As quantified by fractal/generational branching analysis using the computer code VESGEN, vascular density increased maximally at low VEGF concentrations, and vascular diameter increased most at high VEGF c...

|Collisional Removal of O2 (c(sup 1) Sigma(sup-)(sub u), nu=9) by O2, N2, and He - Copeland, Richard A.|
The collisional removal Of 02 molecules in selected vibrational levels of the c state is studied using a two-laser double-resonance technique. The output of the first laser excites the 02 to nu = 9 or 10 of the c Sigma - state, and the ultraviolet output of the second laser monitors specific rovibrational levels via resonance-enhanced ionization. The temporal evolution of the c Sigma u state vibrational level is observed by scanning the time delay between the two pulsed lasers...

|Dust Devils on Mars: Effects of Surface Roughness on Particle Threshold - Neakrase, Lynn D.|
Dust devils have been proposed as effective mechanisms for lofting large quantities of dust into the martian atmosphere. Previous work showed that vortices lift dust more easily than simple boundary layer winds. The aim of this study is to determine experimentally the effects of non-erodable roughness elements on vortex particle threshold through laboratory simulations of natural surfaces. Additional information is included in the original extended abstract.
